によって支持されている。The elbow connecting pipe 15 is attached to a support member 19 fixed to the floor surface.
Supported by
直線接続管１２及び１４の端部（押出機１１及び１３と
連結された端部とは反対側の端部）はエルボ−接続管１
５の内径部にはめ合わせである。The ends of the straight connecting pipes 12 and 14 (the ends opposite to the ends connected to the extruders 11 and 13) are connected to the elbow connecting pipe 1.
It fits into the inner diameter part of No.5.
第３図にエルボ−接続管１５を拡大して示す。FIG. 3 shows an enlarged view of the elbow connecting pipe 15.
直線接続管１２の先端部の内径穴はテーパ状に拡大して
あり、先端にいくほど肉厚が薄くなっている。The inner diameter hole at the tip of the straight connecting tube 12 is expanded in a tapered shape, and the wall thickness becomes thinner toward the tip.
直線接続管１２の外周部にはみぞ１２ａが設けてあり、
このみぞ１２ａ内にＯ−ＩＪソング０が組み込んである
。A groove 12a is provided on the outer periphery of the straight connecting pipe 12,
O-IJ song 0 is incorporated into this groove 12a.

ルボ−接続管１５にボルト２２及びナツト２３によって
取り付けられたパツキン押え部材２４によって所定位置
に保持されている。A gland packing 21 is arranged and buttoned at the entrance of the inner diameter of the elbow connecting pipe 15, and this gland packing 21 is held in a predetermined position by a packing holding member 24 attached to the elbow connecting pipe 15 with a bolt 22 and a nut 23. has been done.
直線接続管１４とエルボ−接続管１５の連結部も上記と
同様の構成としである。The connecting portion between the straight connecting pipe 14 and the elbow connecting pipe 15 has the same structure as above.
次に、作用についか説明する。Next, the effect will be explained.
ジャケット１６内の蒸気によって直線接続管１２が加熱
されると、直線接続管１２は熱膨張して長くなる。When the straight connecting tube 12 is heated by the steam in the jacket 16, the straight connecting tube 12 thermally expands and becomes longer.
直線接続管１４の一端は押出機に固着しであるので、熱
膨張によシ長くなった分だけ先端部が第３図中で右方向
に移動する。Since one end of the straight connecting tube 14 is fixed to the extruder, the tip moves to the right in FIG. 3 by the length of the tube due to thermal expansion.
先端部は何の拘束も受けず自由に伸長するので、直線接
続管１２には熱応力は全く発生しない。Since the tip extends freely without any restraint, no thermal stress is generated in the straight connecting tube 12.
直線接続管１２の先端部の肉厚は先端にいくほど薄くし
て剛性を小さくしである。The wall thickness at the tip of the straight connecting tube 12 is made thinner toward the tip to reduce rigidity.
従って、流動する溶融樹脂の圧力によって先端部は容易
に押し拡げられてエルポー接続管１５の内径部に密着す
る。Therefore, the tip portion is easily expanded by the pressure of the flowing molten resin and comes into close contact with the inner diameter portion of the elbow connecting pipe 15.
これによって、はめ合わせ部のシールが確実に行なわれ
る。This ensures that the fitting portion is sealed.
はめ合わせ部にＦｉＯ−リング２０及びグランドパツキ
ン２１が設けられて釦す、樹脂の漏れ防止及び気密の保
持が完全に行なわれる。A FiO-ring 20 and a gland packing 21 are provided at the fitting portion to completely prevent resin leakage and maintain airtightness.
直線接続管１４とエルボ−接続管１５との間でも上記と
同様の作用が得られる。The same effect as described above can be obtained between the straight connecting pipe 14 and the elbow connecting pipe 15.
